What this interaction means in plain words
Antipyrine and Metoprolol have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Metoprolol may reduce hepatic blood flow and modestly decrease oxidative metabolism of antipyrine.
